MAKE THE POTATO SALAD
Boil the potatoes whole with the skin on in salted water for about 15 to 20 minutes, or until fork tender in the center. The bigger your potatoes, the longer they will take.
While the potatoes boil, dissolve the chicken bouillon cube in the boiling water in a small bowl. Then whisk in the rice vinegar, mustard, neutral oil, sugar, salt, and pepper to make the dressing.
Once the potatoes are cool enough to handle, peel them. Slice into 4 wedges, then cut each wedge into slices about 1/4-inch thick.
Add the warm potatoes, sliced red onion, and chives to the dressing. Toss it all together and let it sit so the potatoes absorb all the flavor.
PREPARE THE CUTLETS
If using a whole cut like veal top round or leg, slice it into pieces about 1/4-inch thick.
Place between parchment or plastic wrap and pound until very thin, about 1/8-inch thick. The cutlet should be wide and even. If you prefer it a bit thicker, you can leave it at 1/4-inch thick.
Lightly season both sides with salt and pepper.
SET UP THE BREADING STATION
In one bowl, mix flour with salt and pepper.
In a second bowl, whisk eggs with milk, a pinch of salt, and pepper.
In a third bowl, combine breadcrumbs with salt and pepper.
BREAD THE SCHNITZEL
Begin by heating enough neutral oil with clarified butter so the cutlets can float in the pan over medium heat.
While the oil heats, dredge each cutlet in the flour, shaking off excess. Do not press it in. Make sure to use one hand for the dry and the other for the wet.
Dip into the egg, letting the excess drip off.
Coat in breadcrumbs, gently tossing to coat. Do not press the breadcrumbs in.
FRY THE SCHNITZEL
Once the oil is hot enough, add 1 or 2 cutlets at a time depending on the size of your pan and the cutlets. Do not overcrowd and fry in batches as needed.
Gently shake the pan back and forth as it cooks so the hot fat moves over the top of the cutlet.
Fry until golden and crispy, about 2 minutes per side.
Transfer to a wire rack baking sheet to drain any excess oil and to keep it crispy while the rest are fried.
ASSEMBLE
